Hello, I believe I may have found a new, older use of the concept of tin foil hats dating back to 1863, just under half a century older than the oldest reference currently in this article. It is in the book "Hedderwick's Miscellany of Instructive and Entertaining Literature", p.334. The book doesn't discusses tin foil hats in reference to the common stereotypes associated with them today but rather "Building a ferocious monarch". I don't know if this is actually related or just tin foil hats being used in some unrelated way but though it could be useful to mention. Feel free to check out the source and determine whether it should be added to the article or just ignored. Resolving ( talk) 07:28, 18 October 2019 (UTC) reply

Specifically /info/en/?search=Slave_Ship_(Pohl_novel) where toward the end of the novel, telepaths (including the protagonist) must use close-fitting tin-foil hats (not the "dunce cone" type shown in this article, but an all-over wrap) to protect themselves from the invading extraterrestrials. What I don't know is whether this is an inspiration for or inspired by the anti-government thing. (Or, indeed, if they are both derived from something earlier.)

There's an addition at the end of the end of the first paragraph that is an united opinion: "as well as a popular derogative to shame out holders of dissident views, similar to former days' disciplinary use of a dunce cap." There is also an almost identical addition at the end of the first paragraph in the second section. Toadrain ( talk) 19:49, 12 February 2022 (UTC) reply

Can't find it now, but there was an item on line from about 2009 allegedly where some people from MIT had done some personal experiments for the heck of it with decent instrumentation that showed that because the cap was not a fully contiguous spheroid, it did not exhibit Faraday Cage shielding effect, but actually amplified the signal inside it. It was also mentioned in some newspaper articles. If someone has more time and interest it is worth considering including it in the article, at my age, I have other interests. 60.241.34.251 ( talk) 11:24, 12 July 2024 (UTC) reply
